Optimus Prime

Autobot

Function: Leader

When Optimus Prime crashed to Earth with the rest of the Autobots, he
didn't really know what it meant to be a hero. He spent most of his
time in space dreaming of glory, but it wasn't until he was first faced
with the terrible decisions that inevitably come with leadership that
he finally understood. He became a true hero - a being who does what he
does not for glory and fame, but because no-one else can do it.
